<h1>Module <code>resty.cassandra.policies.lb.req_rr</code></h1>
<p>Request-aware round robin load balancing policy for OpenResty.</p>
<p> This policy will try to reuse the same node for the lifecycle of a given
 request if possible. It is mostly designed for use in OpenResty
 environments.</p>

<p> This ensures that the underlying connection pool to the node is reused as
 much as possible. If a new node is chosen for every query, there is no
 guarantee that each selected node will already have a pre-established
 connection. Since this policy reuses the same node for the lifecycle of a
 request, the chances of having to open a new connection are much reduced.</p>
